Bestehende Ansätze zur Modellierung wissensintensiver Geschäftsprozesse versuchen dem Charakter dieser Prozesse durch spezielle Konzepte und Methoden in der Modellierung gerecht zu werden. Dabei unterscheiden sich die Ansätze je nach Fokus der Modellierung erheblich. DeCo und KIPN zum Beispiel empfehlen eine Lockerung der Kontrollflussorientierung. KMDL(More)
Though knowledge management (KM) and knowledge management systems (KMS) have been well established in organizations the question on how to evaluate the benefits to be gained from the use of such systems is still not finally resolved. Based on a complete case study showing how a KMS was introduced in a knowledge-intensive small enterprise in Germany this(More)
In this paper, we present a formal metamodel-based approach for modeling and executing ConcurTaskTrees (CTT). CTT is a modeling language for tasks that represent hierarchical tree-like, structured workflow models. In the metamodel soundness properties as well as operational semantics of the workflow language are captured. The models are created with an(More)
While Ontology Design Patterns (ODPs) are intended to support the process of ontology engineering, they can also be used in order to improve existing ontologies. This paper describes strategies for the selection of candidate ODPs that qualify for the improvement of a given ontology. Starting point is the ExpertFinder ontology that allows for competency(More)
Technological innovations in the area of wireless sensor networks, which allow for features like spontaneous networking and self-organization, are enablers for new kinds of IT services in many application domains. In order to fully exploit the potential of these technologies various industries show examples for innovations on the level of service management(More)
Ontology Design Patterns (ODPs) provide best practice solutions for common or recurring ontology design problems. This work focuses on Content ODPs. These form small ontologies themselves and thus can be subject to ontology quality metrics in general. We investigate the use of such metrics for Content ODP evaluation in terms of metrics applicability and(More)
While the main purpose of Ontology Design Patterns (ODPs) is to support the process of ontology engineering, they can also be used to improve existing ontologies. This paper has a focus on ODP selection and integration for ontology improvement. Based on the case of the ExpertFinder ontology, which allows for competency description of researchers, selection(More)
